portion of the clutch building mechof the machine. This box containsvarious drives,

and working parts relating to the bunch builder mechanism, as willafterwards be referred to.

Proceeding out of the gear box at the front are winding spindles 2 whichare driven by mechanism within the gear box. These spindles co-operatewith mechanism, not here shown but described in my said application, forholding the bobbins 3 during the winding operation, and from which thewound bobbins are released at the termination of the wind. Proceeding,also, from out of the front of the gear box, in determinate relation tothe spindles and bobbins driven thereby, are traverse bars 4 on whichare mounted carriers which bear the guides for the thread as it is woundupon the bobbins. Suitable bearings are provided for the ends of thesebars. The traverse bars have both a rotary and reciprocative movementduring the winding operation. They are rotated from oil gears 5 in thegear box and reciprocated from off a cam 6 within the same box.

Each traverse guide rod 4 is exteriorly threaded in part, and located onthe part thus threaded is slidably arranged a thread guide carrier 8.Each of these carriers bears at the right and left two projecting threadeyelets 9, which extend over the positioned bobbins 3 and allow thethread to run onto the bobbins during the winding operation. The threadguide carrier has pivotally attached to it a thread carrying arm I lwhich is movable into and out of engagement with the threads on thetraverse bar. When the arm is out of engagement with the traverse barthen the thread guide carrier may slide thereon. The arm I! of eachthread guide carrier is positioned and controlled by means of a threadguide carrier release rod 2. As the position of this rod 12 isrelatively changed, the thread carrying arm ll of the thread guidecarrier will have engagement or disengagement with the threads on thetraverse bar, engagement as the rod l2 is'moved down, i

and disengagement as the rod I2 is moved up. When the thread carryingarm ll of the thread guide carrier is in engagement with the threads onthe traverse bar then the carrier and thread guides carried by it willbe reciprocated by the reciprocation of the bar, and will have,'also, aprogressive outward movement along the bar for 'sively on the traverseobtaining a progressive wind upon the bobbin.

the body of the thread guide carrier and at itsopposite end against anabutment it on the traverse bar. When the winding is initially startedthe thread guide carrier is then occupying a position in the vicinity ofthe gear nor; with bearing against a stop it adjustably mounted on therod ill. The progressive winding of the bobbin will continue until thethread guide carrier engages a stop ll, when, through mechanismpresently to be referred to, the thread guide carrier release rod it,which controls the position of the arm M, will be actuated to lift thisarm into disengagement with respect to the threads on the traverse bar.Thereupon the return spring it on the traverse bar will return thethread guide carrier back to its initial position with bearing againstthe stop it.

The thread guide carrier release rods it are borne by crank arms it inwhich the opposite ends of the rods are arranged, and to which "they arefixed. All the crank arms are provided with axles it by which they mayturn. The axles to the crank arms at the fore ends of the release rodsturn within arms it on the frame of the machine. At the opposite ends ofthe release rods the axles of the crank arms turn within bearings on thefront of the gear box, and one of these axles, or an axle it extendsthrough its bearing into the interior of the gear box. Arranged upon theaxle it, inside the gear box, are various parts of the bunch buildermechanism later to be referred to. The crank arms is are connected toturn in unison by a linkage 2i. When the crank arms are rocked in aclockwise direction as viewed from the front of the machine, the releaserods lZ carried by them will be raised and will thereby release the armsll of the'thread guide carriers for engagement with the threads of thetraverse bars. Reversely, when the crank arms are rocked in ananti-clockwise direction the engagement between the arms M of the threadguide carriers and the threads of the traverse bars are restored. Arocking motion is imparted to the crank arms by a rock shaft 24.Thisshaft is mounted to rock within suitable bearings on the frame ofthe machine and is rocked back and forth in the operation of the machineat timed intervals, dependent upon the starting and completion of thewind. When the wind is completed and the thread guide carrier is broughtinto engagement with the stop ll, thereupon, in the operation of themachine the rock shaft will be turned in a clockwise direction. The rockshaft has secured to it downwardly extending lever arms iii-which turnas the rock shaft is turned. Pivotally connected to the ends of theselever arms is the linkage it which connectswith the crank arms l8.Consequently all the crank arms it will be .i lmed in a clockwisedirection as the rock shaft 24- is turned in a clockwise direction;thereby elevating the thread guide carrier release rods i8 and movingthe arms ll of the thread guide carriers into disengagement with thethreads of the traverse bars. As the operation of the machine continuesthe spindles will be replenished with a fresh set of bobbins, thepreviously wound bobbins having been removed. Preliminary to startingthe operation of the spindles and traverse bars, for winding the freshset of bobbins, the rock shaft 2% will lti aaraoco in the operation ofthe machine be turned in an anti-clockwise direction and through theconsequent reverse turning of the crank arms it will allow engagementbetween the arms ii of the thread guide carriers and the threads of thetraverse bars.

Reference will now be made to the mechanism which actuato s the rockshaft 2 3, although for a complete description of this mechanismreference is made to my said application. Connected to one end of therock shaft is a lever arm 2% which will hereinafter be sometimesreferred to as the control lever. This control lever, as will presentlybe explained, is a spring activated lever. it bears a stud ii which,when the lever is turned down against the tension of its controllingspring with consequent anti-clockwise turning of the rock shaft 2Q, willbecome locked to a fork 2d. The control lever is unlocked from this forkat the end of the wind when the thread guide carrier strikes the stopll. Thereupon the control lever, tensionally controlled as aforesaid,will rise with consequent turning of clockwise direction.

The tensional control of the control lever and its return from anunlocked position to a locked position with the fork, from which it hasbeen previously released, is brought about by the'following describedmechanism. Fixed to the end of the rock shaft it opposite that end towhich thecontrol lever it is fixed is a lever arm til in direct opposingrelation to the control lever arm 26, the two arms combining to form acomplete control lever. At its end the arm it is connected through afolding joint ii to a two-armed lever s2 which lies in extension of thecontrol lever to which it is attached and i pivotally mounted in thebed. of the machine. when the control lever 25 is released from itslocked engagement with the fork is the lever will rise while the arm tilof the complete control leverwill move downwardly. The inner arm of thelever 32 will consequently move downwardly and its oumr arm beyond thepoint of its pivotal attachment will move upwardly; On the return of thecontrol lever to its initial locked position a reverse movement of theselevers takes place. The line or levers are under the tensional controlof a spring 35. One end of this spring is secured to the outer end ofthe lever 32. The opposite end of the spring is secured to a cam case35. When the control lever 26 is in locked position with the fork 2d,the end of the lever 32 to which the spring 3 3 is attached will haveheen moved down tensioning the spring. Upon the unlocking of thecontrollever from the fork 28 the then tensioned spring 35, exerting force to'draw upwardly the end of the lever 32, will, through the line of levers,displace the arm 2% of the control lever upwardly from its lockedconnection with the fork and will rock the shaft it to which the controllever is secured in a clockwise direction. Thus it will be seen that theline or levers when locked is under the tensional control of the springlit causing their displacement, as explained, when the arm 26, orcontrol lever, is unlocked from the fork 2%. If new the end of the lever32 be depressed a reverse action of the levers will take place and thecontrol lever- 25 will again become locked to the fork 28 and the rockshaft 24 to which the lever is fixed will beturned in an anticlockwisedirection;

Located above the end of the lever 32 within the case til is a clutchmechanism which is activated by the lever 32 when the arm 26 of the theshaft 2 3 in a control lever is released from it locked engagement withthe fork 28, and which clutch mechanism is thrown out or disengaged whenthe arm 26 of the control lever is returned to its lockingv engagementwith the fork 28. The clutch mechanism includes a continuously rotatingworm wheel 38 which is driven by a worm 39 on a shaft 40 turned in anysuitable manner in the operation of the machine. The worm wheel 38 isjournalled to turn on the casing 35 and carries on its under side one ormore pins 4|. Beneath the wheel 38 is located a freely rotatable camdisk 42 which bears a pin 43. This pin is adapted to have clutchengagement with one of the pins 4| on the continuously rotating wheel 38when the cam disk is lifted, whereupon during the continuance of suchengagement the cam disk 42 will be rotated by the wheel 38. The cam diskis lifted by the outer arm of the lever 32 as this arm turns upwardly onthe release of the control lever arm 26 from its locking engagement withthe fork 28. The outer arm of the lever 32 has secured to it a rollerfinger 45 which extends laterally beneath the cam disk 42 and acts tolift the disk as the arm becomes lifted. The cam disk 42 isheld againstrotation by a stop 41 on the body of the frame of the machine whichenters a slot 48 in the edge of the disk. When the stop is in this slotthe cam disk cannot be turned. The cam disk can be turned when the leverarm has lifted it above'the plane of the stop 41 at which time the diskwill be thrown into clutch. engagement with the rotating wheel 38 and beturned thereby. The action is one in which the cam disk 42 is made tohave only a single complete revolution after the throwing in of theclutch, disengagement or throwing out of the clutch being effected atthe completion of such revolution. To this end the cam disk is formed onthe under side thereof with a projection or cam 50, which, when the camdisk is approaching the end of its single revolution will enter betweenthe disk 42 and the finger 45 on the forward arm of the lever 32 anddepress this arm, thereby turning the lever 32 and returning the arm 28of the control lever again into locked engagement with the fork 28. Thecomplete revolution of the cam disk 42 will now have brought the slot 48in the edge of the disk into alignment with the stop 4'! on the frame,whereupon the cam disk 42 will be thrown out of clutch engagementwitnthe wheel 38 by means of an arm 52. This arm is pivoted to thecasing 35 and the end of the arm has drawing engagement with the top ofthe cam disk 42 by means of a spring 53, one end of which is connectedtothe. end of the lever 52, and the other to the fore end of the lever 32.

While various operations in the complete operation of the machine arebrought about, as re- .ferred to in my said application, through changein the location of the chain of levers just referred to following theunlocking of the control lever 26 from the fork 28 on the completion ofthe wind, including the disengagement-of the arms H of the thread guidecarriers from the traverse bars, the stopping of the winding spindlesand traverse bars, followed by the release of the wound bobbins, and thereplenishment of the winding spindles with fresh bobbins to be wound;after which, upon restoration of the control lever to locked engagementwith the fork, the operation of the winding spindles and that of thetraverse bars will be restored, and, if no bunch is to be formed, thearms ll. of the threadguide-car riers will be moved down to haveengagement with the threads on the traverse bars, yet, the part which isespecially pertinent to the present case of bunch building centersaround the operation of the rock shaft 24, and appurtenant thereto.

If no bunch building is desired on the bobbins, with no bunch builderattachment to the machine, then a progressive wind on' the bobbins willstart'immediately when the arms ll of the thread guide carriers 8 arepermitted to have engagement with the threads of the traverse barsthrough the lowering of the thread guide carrier release rods I2, thespindles and traverse bars having then been thrown into operation. When,however, a bunch is to be built upon the bobbins the lowering of thethread guide carrier release rods which throws the arms I l ofthe threadguide carriers into engagement with the threads of the traverse bars issuspended until the bunch has been formed, although the rock shaft 24 inthe operation of the machine has been turned in an anti-clockwisedirection to obtain such engagement. This suspension is brought about bylocking the crank arm axle HI which extends into the gear case for atimed interval, or during the building of the bunch. The locking of thisaxle and the period during which it will remain locked is obtained byvarious parts of the builder mechanism located on or about the axlewithin the gear box I and to which detailed reference will later bemade. The locking of the crank arm I9 is rendered possible by anestablishment of lost motion between the arms 25 on the rock shaft 24which connect with the crank arm 18 through the linkage 2 I, aspreviously described. This lost motion is brpught about by slots 25' inthe linkage 2|, the pin connection between the arms 25 and the linkagerendering through the slots when the rock shaft is turned in ananti-clockwise direction. The

rock shaft 24 will then exert no force to turn the crank arms l8 andpermits of the locking of the axle I9 and temporary fixing of all thecrank arms.

During the period of suspension just referred to, inasmuch as thethreads on the traverse bar cannot be relied upon to reciprocate thethread guide carriers during the building of the bunch,

, other means must be relied upon to obtain such reciprocation, and tothis reference will first be made, reference being afterwards made tothe manner in which the axle IE! is locked, the means for obtaining atimed interval'for its locking, and the subsequent release of this axleand consequent turning of the crank arms permitting of engagementbetween the arms ll of the thread guide carriers and the threads of thetraverse bars as the progressive wind on the bobbins continuesimmediately upon the completion of the building of the bunch. First,however, with reference to the mechanism for reciprocating the threadguide carriers during the building of the bunch.

Arranged to turn in brackets 55 on the face of the gear box I is arocker shaft 58 which is located above the thread guide carriers andbetween them and the face of the gear box. This rocker shaft carriesrockers 51 which bear, respectively, against the backs of the threadguide carriers and move them along the traverse bars as the rocker shaft56 is rocked. Reverse movement of the carriers, after being movedforward by the rockers, is obtained by the action of the then tensionedtraverse springs I 4. Therocker shaft 56 is'rocked by means of a bentlever 58 the parts directly pivotally hung from off a shaft 60, the endsof which are supported within brackets BI fixed to the face of the gearbox. This shaft is arranged above the rocker shaft 56 and between it andthe gear box. The pivotal mounting of the lever 59 is such that it maybe swung laterally into contact with the traverse bar, and it isnormally urged in the direction of the traverse bar by a flat spring 62connected to it and which bears against the shaft 60. Arranged upon thetraverse bar is a collar 64. As will presently be explained, during thebuilding of the bunch the lever 59 is maintained in a position justclear of the traverse bar, in the direction of which it is urged by thespring 62, where it may be struck by the collar 64 on the traverse baras the traverse bar is reciprocated. and which will accordingly rock thelever 59. The rocking movement of the lever 59 is imparted to therockershaft 56, for rocking it, through an arm 55 on the rocker shaft 56 whichhas a link connection 59 with the lever 59. The normal at rest positionof the lever 59 is against a block Gll forming a stop on the rockershaft 59, and the lever is held to yieldingly bear against this stop bya coil spring 56' on the shaft 56, one end of which is secured to theshaft and the other end to the adjacent bracket 55 within which theshaft is turning, the spring acting through the rocker shaft 55 andthrough the arms 65 and 96, which form the link connection between therocker shaft 56 and the lever 59, to normally hold the lever 59 inplace. From its normal at rest position the lever 59 is displaced by.the collar 54 on the traverse bar. With the parts thus arranged anddisposed, and working in co-operation with the traverse springs motionwill be imparted by the traverse bars as they are reciprocated toreciprocate the thread guide carriers .for effecting a traversing lay ofthread for forming the bunch on the spindles.

In this connection it is obvious that the length of thebunch may be madeto depend upon the extentof movement of the rockers 51, and'this willdepend upon the point, or points, where the link 66 makes connectionwith the arm 95, or with the lever 59, or with both of these elements,the extent of leverage for rocking the shaft 56 being thereby increasedor diminished.

During the period that the lever 59 is beingmoved, when contacted by thecollar on the traverse bar during the reciprocation thereof, the leverwill bear not against the traverse bar, but will have sliding contactwith a bar 58 on the linkage 2! which connects the crank arms Hi. Whenthe control lever 26 is returned to its locked position with the fork28, the rock shaft 24 will be turned in an anticlockwise direction withthe effect of drawing the linkage 2i to the right, as viewed from thefront of the machine. As the linkage draws to the right the bar 58 willbe brought into a position where the lever 59, then released, willcontact with the edgeof the bar and be maintained in a position justclear of the traverse bar and so that it may be struck by the collar onthe traverse bar as this bar is reciprocated. The bar 68 accordinglyfunctions both as a stop for the lever 59 and, also, as a slide on whichthe lever may move just clear of the traverse bar. The lever 59 is underthe control of a withdrawal arm 10. This arm extends upwardly from theinner end of the rock shaft 24. Connected to the upper end of thiswithdrawal arm is a link H which is secured to an angle plate 12fastened to the lever 59 below the point of its pivotal connection tothe shaft 60. When the control lever is released from its lockedconnection with the fork 28 on the termination of the wind and the rockshaft 24 is thereby turned in a clockwise direction, the withdrawal arm10 on the rock shaft will then be turned to draw the lever 59 into adisengaging position with relation to the collar on the traverse bar.

The lever 59 is also moved into a disengaging position with relation tothe collar on the traverse bar during the period of the wind after thecompletion of the building of the bunch. This effect is obtained by aforward movement of the bar 68 against which the lever 59 is bearingduring the building of the bunch. When the control lever is returned toits locked position with the fork 28, preliminary to starting a freshwind, the rock shaft 29 will be turned in an anti-clockwise directionand consequently will tend to draw the linkage 2i to the right and willexert drawing effect thereon suflicient to move the bar 69 carried by itinto a position where it will act as a stop for the lever 59 thenreleased to bear'ag'ainst the stop, or in a position where it may bestruck by the collar on the traverse bar as the bar is reciprocated. Thenormal action of the rocker shaft 29, preliminary to the beginning of awind, if no bunch is to be built, is through the linkage 2l,to move thecrank arms l8 sufliciently to allow the thread carrying arms of thethread guide carriers to have biting contact with the threads on thetraverse bars. But as previously explained,

this action is suspended during the building of the bunch through thelocking of'the shaft N to the axle of one of the crank arms.Accordingly, the crank arms, not being completely turnable until thebunch has been built, or not turnable to an extent sufficient to allowengagement between the thread carrying arms of the thread guide carriersand the thread on the traverse bar, are still turnable in an amountsuificient to have moved the linkage 2!! to locate the bar 68 where itwill act as a stop and slide for the lever 59 during the building of thebunch. When the bunch has been built, however, and the axle l9 released,which enables the crank arms E8 to complete their turning, thereupon thelinkage 2! will have a further slight movement to the right, or onesufiicient for the bar 58 to move the lever 59 out of the contact rangeof the collar on the traverse bar marking the completion of the bunchbuilding traverse, and at which same time the thread carrying arms ofthe thread guide carriers will have moved down, by the then permittedlowering of the rods 12, to have biting engagement with the, threads onthe traverse bars which marks the beginning of the progressive windwhich immediately follows the building of the bunch.

Reference will now be made to the manner in which the axle I9 is locked,to the manner of obtaining a timed interval for its locking, and to thesubsequent release of this axle and consequent turning of the crank armsI8 permitting of.;;the fall of the rods lZE-and engagement between thearms H of the thread guide carriers and the threads of the traverse barsas the progressive wind on the bobbins continues immediately followingthe building of the bunch. Secured to the end of the axle I9 inside thegear. box is a looking arm 15. This locking arm is under the control ofa spring 16, one end of which is secured to the arm and the other end toa fixture IT located within the gear box. lT'he spring is tensioned' andtends to draw thearm to the left, as viewed from the front of themachine. Located within the gear box is a bracket 19. Pivotally mountedupon this bracket is a combination keeper and lock release element 80with which the locking arm 15 co-operates and which is provided with adownwardly extending wing extension 8|. The element 88 is under thetensional control of a spring 88. The turning of the axle I9 iscontrolled by this element 80 through the engagement of the locking arm15 therewith. When the rock shaft 24 is turned in a clockwise directionfollowing release of the control lever 26 at the termination of thewind, thereupon the locking arm 75 on the end of the axle ill will beturned in a clockwise direction withinthe housing formed by the element88. When now the rock shaft 24 moves in an anti-clockwise directionfollowing the restoration of the control lever 26 to its locked positionwith the fork 28, thereupon the locking arm 15 will be turned to theleft, or in an anti-clockwise direction, until it engages a shoulder 83on the inside face of the element 88, preventing further turning of thearm and consequently further turnin of the axle [9. All the axles of thecrank arms I8, will then be locked to prevent their further turning, orsuch turning as will allow the drop of the rods l2 to permit ofengagement between the thread carrying arms I I 'of the thread guidecarriers and the threads of the traverse bars. Loosely arranged upon theaxle l9 is a ratchet wheel 85 under the control of a return spring 86.Secured to project from the side of this ratchet wheel is a stud 81. Theratchet wheel is turned by means of a spring controller feed pawl 88borne by a feed pawl arm 89 under the control of a reciprocating crankarm 90. This crank arm is vibrated in any suitable manner from offmechanism within the gear box which drives the spindles and traversebars. As the feed pawl 88 is oscillated it turns the ratchet wheel 85which is also under the control of a spring controlled ratchet releasepawl 9|. When the feed pawl 88 has turned the ratchet wheel 85 in adeterminate amount, or for a determinate interval of time, the stud 81borne by the ratchet wheel will be brought into engagement with thebottom edge of the wing 8| to the element 80. Thereupon upon slightfurther turning of the ratchet wheel the element 88 will be liftedreleasing thelocking arm 15 from engagement with its shoulder 83 andpermitting further turning of this arm and the axle 19 in ananti-clockwise direction. This permits such further turning of the crankarms l8 as will drop the rods l2 to permit of engagement between thethread carrying arms H of the thread guide carriers and the threads ofthe traverse bars, marking the beginning of the progressive wind. Thelifting of the element 88 tends also to release the feed pawl 88, andalso the ratchet release pawl 9| from engagement with the ratchet wheel.The feed pawl 88 during its operation for turning the ratchet wheel hassliding contact by a tongue 92 on it with the edge of the element 80 sothat when this element is lifted the tongue will move the pawl 88 out ofoperative contact with the ratchet wheel. The release pawl 9i is mountedon the element 80 and is provided with a similar tongue 93 so thatlifting the element 80 releases this pawl from the ratchet wheel. Withthe pawls thus disconnected from the ratchet wheel it will be returnedby its return spring 88 to the point of its starting. The time intervalfor forming the bunch depends upon the amount under the control of asetting wheel 94.

ing operation culminates when the element 88 is lifted, whichreleases'the feed pawl 88 from the ratchet wheel. The amount theratchetswheel is turned depends upon its starting point and this is Thissetting wheel is loosely arranged on the axle l9 and bears on its sidefacing the ratchet wheel a stud 95. The ratchet wheel in turn, on itsside facing the setting wheel, is provided with a stud 96 which, as theratchet wheel is returned by its return spring 86, will engage the studon the setting wheel, which determines the starting point of the ratchetwheel, this in turn depending upon the turned position of the settingwheel. The setting wheel is provided with a serrated edge 91 and is heldin any determinate turned position by a pin 98 which fits in any one ofthe openings in its serrated edge for thus locating it in anydeterminate turned position, depending upon the desired location of thestud 95 carried by it. The pin 98 is borne by a stationary arm 99 fixedto extend from the bracket 19.
